%X The absorption of nitrogen(N) and phosphorus(P) by Hydrodictyon reticulatum was studied under laboratory conditions, and field studies were carried out simultaneously in a eutrophic reservoir in south China to assess its growth ability. Results showed that the optimal N:P ratio was 15 for its growth. Hydrodictyon reticulatum absolved phosphorus very rapidly, and almost removed phosphorus off thoroughly at various N:P ratios after growing three days. Removal rates of TN were all above 74% at various N:P ratios and almost up to 100% when TN and TP concentrations were 4.5mg/L and 0.3mg/L respectively. It was found that the algae assimilated ammonium preferentially when ammonium and nitrate were simultaneously used as nitrogen sources. Hydrodictyon reticulatum grew well in the reservoir and its growth rates were 1.051, 0.557 and 0.333 in summer, autumn and winter, respectively.
